Background

Marc Wefers is a Principal in the Boston office of Fish & Richardson. He joined the firm in 1996, having previously served as an associate, patent agent, and technology specialist with the firm.

Marc’s practice focuses on patent strategy, including patent prosecution, adversarial proceedings before the United States Patent and Trademark Office (USPTO), and litigation, especially in the technical areas of physics, optics, and chemistry. Marc has been lead counsel on four interferences before the USPTO, obtaining a favorable judgment in every instance, one of which was appealed and affirmed at the United States Court of Appeals for the Federal Circuit. Marc has also been lead counsel on ten inter-partes review (“IPR”) proceedings at the USPTO, two for Petitioner and eight for Patent Owner.

Prior to such AIA proceedings Marc was involved in many reexamination proceedings at the USPTO. Marc has also been the technical lead in various patent litigations relating to fiber lasers, fiber amplifiers, and microlithography exposure systems.
